Queen Elizabeth II's granddaughter Zara Tindall is pregnant, a spokeswoman confirmed to the U.K.'s Press Association. Tindall and her husband of six years, rugby player Mike Tindall, also have a 3-year-old daughter, Mia Tindall, who will celebrate a birthday this month.

Zara, who is 16th in line to the British throne, is the only daughter of the queen's only daughter, Princess Anne. Meanwhile, the monarch is gearing up to welcome not one, but two new great-grandchildren into the royal kin.

It has been reported that Zara's expected due date falls in the summer, leaving some room in between the births. The accomplished equestrian unfortunately suffered a miscarriage in December 2016, a month after they publicly confirmed the pregnancy.

It's shaping up to be quite a big year for the royals as not only are two babies on the way, but also a wedding! As most are well aware at this point, Prince Harryand his American leading lady, Meghan Markle, will tie the knot on May 19.
